Texas Power Demand Hits 91,308 MW — Why Bitcoin Miners Are the Grid's Newest Emergency Brake

Texas broke its all-time electricity demand record twice in two days last week, hitting 91,308 megawatts around 5 p.m. on July 22. This surge erased the previous record of 85,508 megawatts that had stood since August 10, 2023 (CryptoSlate).

Demand Could Double by 2032 — The Grid's Capacity Crisis

The Electric Reliability Council of Texas (ERCOT) (the nonprofit corporation that manages the flow of electricity for 90% of the Texas load) informed regulators that demand could roughly double within six years to reach 175,000 megawatts (CryptoSlate). This projected growth forces a massive rework of long-term forecasts, as previous estimates for 2032 were deemed flawed by regulators (CryptoSlate).

Every all-time peak ERCOT has ever recorded arrived during the heat of July or August. Last week's peak arrived at 5 p.m., a critical window where solar output falls toward zero while air conditioning demand remains at its highest (CryptoSlate).

The current system carries more than 20 gigawatts of headroom at peak, but this buffer is increasingly reliant on voluntary shutdowns from large-scale energy consumers. These consumers are primarily Bitcoin mining facilities that participate in curtailment agreements (CryptoSlate).

Curtailment Credits Generated $56.7 Million in 2025 — A Vital Safety Net

Bitcoin mining has become a cornerstone of Texas's grid stability through voluntary curtailment agreements (CryptoSlate). These agreements allow ERCOT to pay large customers to power down during periods of scarcity, effectively acting as a non-mechanical emergency brake.

The financial incentive for miners to shut down is tied directly to the profitability of their operations. Hashprice (the daily revenue a miner earns from a petahash per second of computing power) recovered to roughly $32 in recent weeks (July 2026), up from a 2026 low of $27.20 in early June (CryptoSlate). However, this remains 35% below the $49.40 recorded last October, meaning a shutdown is often cheaper for miners than continuing to mine (CryptoSlate).

Riot Platforms demonstrated the massive scale of these credits during the August 2023 heat wave (CryptoSlate). The company reported $31.7 million in total revenue for that month, with $24.2 million coming from curtailment credits and $7.4 million from demand response programs (Confirmed — SEC filing). This highlights how mining can be more profitable when the grid is under stress than when it is stable.

The scale of these payments is growing rapidly. Credits reached $56.7 million across 2025 and another $21 million in the first quarter of 2026, representing a 169% increase over the same quarter in 2025 (CryptoSlate).

The AI Pivot Threatens to Disable the Grid's Emergency Brake

The emergence of AI data centers introduces a fundamental risk to the Texas energy landscape. While Bitcoin miners are incentivized to shut down during high-demand periods because their revenue drops, AI workloads are often more rigid and less willing to fluctuate (CryptoSlate).

As mining facilities pivot their infrastructure to support AI, they may move away from the voluntary curtailment models that ERCOT relies on. This shift could strip away the primary mechanism used to manage peak demand without calling for public energy conservation (CryptoSlate).

Texas's unique regulatory environment allows for these experiments, as the state purposefully avoided synchronous connections to neighboring states to maintain independence from federal interstate commerce laws (CryptoSlate). While this isolation allows for unique market mechanisms, it also left the state unable to import electricity during the February 2021 Winter Storm Uri (CryptoSlate).

Winter Demand Profiles Differ from Summer Spikes

The grid faces two entirely different types of stress depending on the season (CryptoSlate). Summer peaks occur in the late afternoon when solar generation fails to meet the cooling load, whereas winter peaks occur in the early morning (CryptoSlate).

The cold-weather record of roughly 78,300 megawatts arrived at 7 a.m. on January 16, 2024, when Texans switched on electric heat before solar power could generate (CryptoSlate). This morning-driven demand profile is much harder to manage via solar-heavy mitigation strategies than the summer afternoon peaks (CryptoSlate).

As the total load grows toward the projected 175,000 megawatts, the margin for error in managing these two distinct peak types narrows significantly (CryptoSlate). The ability of the grid to survive these peaks depends heavily on whether the largest energy users remain willing to turn off.

Key Developments to Watch

• ERCOT (by November 2026) — updates to the long-term demand forecast will determine if current infrastructure investments are sufficient.
• Riot Platforms (Q3 2026) — quarterly reports will show if the trend of increasing curtailment credits continues to outpace Bitcoin mining revenue.
• Texas Legislature (2027) — potential regulatory shifts regarding AI data center zoning and grid interconnection requirements.

As Bitcoin miners transition toward AI, can the Texas grid survive without its most effective, voluntary emergency brake?
